Re: DUV review

Thanks Eric,

If you want to refine the definition of an existing term then making it 
a sub class or sub property of the existing one is the right thing to 
do. That's a good explanation/justification for defining your own terms. 
But if it's just a different word (author cf.creator) then IMO it's not 
a good reason.

dc:hasVersion - yes, fine, sorry, should have thought of that.

But I would always use dcterms rather than dc. dcterms more or less 
supersedes dc, so dcterms:hasVersion works for me.

As for including/not including terms in the diagram - readability makes 
sense and over-complex diagrams are not readable. However, I'd be 
surprised to see terms listed that were not shown in the diagram at all. 
Given the nature of the DUV, with different areas, would it possible to 
'zoom in' to, say, the citation section and in that diagram show all the 
classes and properties?
